研究人员利用1977年至1985年间诊断出的23,567例非西班牙裔白人、2,539例黑人和2,380例西班牙裔乳腺癌病例的信息，评估晚期诊断的风险和诊断前症状持续时间较长的风险与种族、社会经济地位、年龄和诊断年份的关系。所有数据均由南加州大学癌症监测项目收集，该项目是洛杉矶县基于人群的综合发病率登记处。结果表明，较低的社会经济地位、黑人或西班牙裔、较年轻和较早的诊断年份是晚期诊断和症状持续时间长的危险因素。种族的影响不能用黑人或西班牙裔女性较低的社会经济地位水平来解释。在控制症状持续时间后，种族和社会经济地位仍然显著预测更晚期的阶段。在9年的时间框架内，最近的诊断与低社会经济地位的患者的改善阶段无关。这些结果表明，需要加大努力，以达到低社会经济地位和黑人和西班牙裔妇女的运动，提高乳腺癌的发现阶段。
Information on 23,567 Non-Hispanic White, 2,539 Black, and 2,380 Hispanic breast cancer cases diagnosed between 1977 and 1985 was used to evaluate the risk of late stage diagnosis and long duration of symptoms prior to diagnosis in relation to ethnicity, socioeconomic status, age and year of diagnosis. All data were collected by the University of Southern California Cancer Surveillance Program, the comprehensive population-based incidence registry of Los Angeles County. The results indicate that lower socioeconomic status, Black or Hispanic ethnicity, younger age, and earlier year of diagnosis are risk factors for late stage diagnosis and long duration of symptoms. The effect of ethnicity was not explained by lower SES levels among Black or Hispanic women. After controlling for duration of symptoms, race and SES remained significantly predictive of more advanced stage. More recent diagnosis across the 9 year time frame was not associated with improved stage for those of low SES. These results suggest that increased efforts are needed to reach low SES and Black and Hispanic women with campaigns to improve the stage at which breast cancer is detected.
